3. Advance the Aspirex device into the proximal occlusion site. During thrombectomy, the Aspirex device should be gently advanced to the distal occlusion site and then pulled back while continuing aspiration. During thrombectomy, rotate the Aspirex device gently to allow for maximum contact of the L-shaped aspiration port with the thrombus. The maximum time for one thrombectomy pass should not exceed 10 seconds to avoid vessel wall engagement during aspiration and unnecessary blood loss. Do not advance the Aspirex device into segmental arteries to avoid perforation or dissection. Thrombectomy should be discontinued as soon as the systemic arterial pressure increases or the pulmonary artery pressure decreases, regardless of the angiographic result. The Aspirex device should not be used without the Terumo wire.
